1) If the IPP printer has an DNS name should there be at least two values
for the printer-uri-supported attribute? One URL with the fully qualified
DNS name the other with the IP address in the URL.
PZ> The printer may contain one or the other or both. See below.
2) Must the operational attribute for printer-uri match one of the values in
PZ> A forgiving printer implementation would not reject the operation. The
printer may not be DNS capable or improperly configured. The request
obviously reached the printer. The printer could treat the printer-uri as
the logical equivalent of a value in the printer-uri-supported. It would be
implementation dependent for which value, and associated security policy,
3) Does this above logic also apply to a job object specified with a
printer-uri and job-id? Is it also true for a job specified with a job-uri?
PZ> Yes and yes
4) Can a restrictive implementation reject a printer or job operation if the
operational attribute printer-uri is not a value of the
PZ> Yes it could, with an error code of client-error-not-found
5) Must the URL in the printer-uri-supported attribute be absolute(i.e.
PZ> Yes. The printer-supported-uri is transformed by well defined rules to
arrive at the address used in the HTTP layer.
